Techrockies has an interview with John Deal, the CEO of Hyperion Power Generation. Below are the highlights with some new information. Hyperion Power generation is trying to make a factory mass produced uranium hydride molten core reactor which will generate 70 MWt and 27-30MWe. Hyperion Power Generation plans to sell and build the first 4000 …
Laboratory experiments show that obstacles arranged in fluids in certain patterns can effectively make objects they surround invisible to waves. If it works as well in in scaled-up versions, it could lead to new ways to protect ocean-based platforms and coasts from devastating tsunamis. Credit: M. Farhat, S. Enoch, S. Guenneau and A.B.

Carnival of Space week 72 is up at twisted physics (Discovery Magazine blog.) This site contributed an update on the solar electric sail project. Colony worlds talks about creating instant roads on the moon and Mars Potentia Tenebras talks about setting bases on near earth asteroids. Check out the Carnival of Space for a lot …
Operating at temperatures just above absolute zero, superconducting cavities accelerate bunches of electrons and positrons toward the detectors in a proposed international linear collider. Nine smooth cells, polished in all possible ways. Made of the purest niobium. Not a speck of dust or the slightest difference in shape. Superconducting when supercold Photo: Fermilab Superconducting cavities …
September 25th, China successfully launched Shenzhou 7 for their first space walk and the first module of a space station. The Shenzhou 7 spacecraft blasted off atop a Long March 2F rocket shortly after 9pm (2300 AEST) under clear night skies in northwestern China. The spacewalk by one of the astronauts is expected to take …

Wired reports that China will build the Controversial Emdrive. UPDATE: The cost and details of superconducting radiofrequency cavities is examined and the potential if the emdrive worksEND UPDATE This site has covered the Emdrive several times before, including the controversy, and the upside. A successful superconducting system would be most efficient at nulling out gravity …
Aquaculture is a major part of the worlds current and future food supply. It currently is the fastest growing food producing sector in the world. Genetically modified (GMO) fish are likely to dominate future fish farming by growing over two times faster than regular fish and being up to 30% more efficient with feed than …
Georgia Tech computer scientists are laying the groundwork for exascale machines that will process more than a million trillion – or 10^18 – calculations per second. Karsten Schwan recently received a 2008 HP Labs Innovation Research Award to work with HP Labs, HP’s central research arm, to help solve some of the key problems in …
How long uranium can supply nuclear power is affected by the kinds of nuclear reactors that are used (Breeder reactors are sixty times more efficient in using nuclear fuel than current reactors) and the sources of uranium that are used and whether thorium can be used to supplement uranium (Thorium can be turned into uranium …
